Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447022, here are decompositions:

3 + 31447019 = 31447022
73 + 31446949 = 31447022
151 + 31446871 = 31447022
163 + 31446859 = 31447022
283 + 31446739 = 31447022
661 + 31446361 = 31447022
769 + 31446253 = 31447022
811 + 31446211 = 31447022

Showing the first eight; more decompositions exist.
